FIELD OF THE DISCLOSURE

Aspects of the present disclosure relate to wireless communications, andmore particularly, to techniques for mobility-aware access control. Someaspects and techniques can be used to enhance mobility-basedcommunication, initial network access, cell (re)selection, and/orhandover procedures when communication components/devices initialcommunications move about or within a communications network.

INTRODUCTION

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,broadcasts, etc. These wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (e.g., bandwidth,transmit power, etc.). Examples of such multiple-access systems include3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE)systems, LTE Advanced (LTE-A) systems, code division multiple access(CDMA) systems, time division multiple access (TDMA) systems, frequencydivision multiple access (FDMA) systems, orthogonal frequency divisionmultiple access (OFDMA) systems, single-carrier frequency divisionmultiple access (SC-FDMA) systems, and time division synchronous codedivision multiple access (TD-SCDMA) systems, to name a few.

These multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent wireless devices to communicate on a municipal, national,regional, and even global level. New radio (e.g., 5G NR) is an exampleof an emerging telecommunication standard. NR is a set of enhancementsto the LTE mobile standard promulgated by 3GPP. NR is designed to bettersupport mobile broadband Internet access by improving spectralefficiency, lowering costs, improving services, making use of newspectrum, and better integrating with other open standards using OFDMAwith a cyclic prefix (CP) on the downlink (DL) and on the uplink (UL).To these ends, NR supports beamforming, multiple-input multiple-output(MIMO) antenna technology, and carrier aggregation.

As demand for mobile broadband access continues to increase, thereexists a need for further improvements in NR and LTE technology.Preferably, these improvements should be applicable to othermulti-access technologies and the telecommunication standards thatemploy these technologies.

SUMMARY

The systems, methods, and devices of the disclosure each have severalaspects, no single one of which is solely responsible for its desirableattributes. Without limiting the scope of this disclosure as expressedby the claims which follow, some features will now be discussed briefly.After considering this discussion, and particularly after reading thesection entitled “Detailed Description” one will understand how thefeatures of this disclosure provide advantages that include improvedmobility-aware access control.

Various aspects or embodiments include a variety of mobility-awarenessfeatures. In some scenarios, these may be utilized in conjunction withand/or for communications in a variety of network arrangements. Forexample, a radio access network may include a wireless backhaul network,sometimes referred to as an integrated access and backhaul (IAB)network. In an IAB network, at least one base station acts as an anchorbase station (also referred to as an IAB donor) that communicates with acore network (via a wired backhaul link). The IAB network may includeone or more non-anchor base stations (also referred to as IAB nodes),that may communicate directly with or indirectly with (for example, viaone or more other non-anchor base stations) the anchor base station viaone or more wireless backhaul links to form a backhaul path to the corenetwork.

IAB networks and communication devices in general, according to someaspects, may include a variety of features related to mobility. Forexample, in a typical IAB network, IAB nodes (for example, non-anchorbase stations) are stationary (that is, non-moving). Conversely, in amobile IAB network, some of the IAB nodes may have mobility capabilities(that is, they may move around in the IAB network). Such IAB nodes maybe referred to as mobile IAB nodes. For example, a mobile IAB node maybe installed on a vehicle (for example, a bus, a train, a taxi) and/ormany other items capable of movement. In a mobile IAB network, there maybe a mix of stationary and mobile IAB nodes.

According to some aspects, components or nodes in a network (e.g., anIAB network) may have a variety of operational states (e.g., a mobilitystate). A mobility state of a given IAB node can impact operation of themobile IAB network. For example, the performance of a number of IABnetwork-related operations may depend on the mobility states of mobileIAB nodes. Such IAB network-related operations may include, for example,IAB topology and resource management, local scheduling, beam management,beam tracking, synchronization tracking, positioning, quality of service(QoS) type support identification, access, and paging, among otherexamples. Thus, knowledge of the mobility state of a given IAB node maybe desirable to facilitate efficient and acceptable performance of themobile IAB network.

DETAILED DESCRIPTION

Aspects of the present disclosure provide apparatus, methods, processingsystems, and computer readable mediums for mobility-aware accesscontrol. For example, a mobility state of an integrated access andbackhaul (IAB) node may impact operation of a mobile IAB network. Forexample, the performance of a number of IAB network-related operationsmay depend on the mobility state of a mobile IAB node.

In some cases, a 5G NR RATnetwork may be deployed.

FIG. 1 illustrates an example wireless communication network 100 inwhich aspects of the present disclosure may be performed. For example,the wireless communication network 100 may be an NR system (e.g., a 5GNR network).

As illustrated in FIG. 1 , the wireless communication network 100 mayinclude a number of base stations (BSs) 110 a-z (each also individuallyreferred to herein as BS 110 or collectively as BSs 110) and othernetwork entities. A BS 110 may provide communication coverage for aparticular geographic area, sometimes referred to as a “cell”, which maybe stationary or may move according to the location of a mobile BS 110.In some examples, the BSs 110 may be interconnected to one anotherand/or to one or more other BSs or network nodes (not shown) in wirelesscommunication network 100 through various types of backhaul interfaces(e.g., a direct physical connection, a wireless connection, a virtualnetwork, or the like) using any suitable transport network. In theexample shown in FIG. 1 , the BSs 110 a, 110 b and 110 c may be macroBSs for the macro cells 102 a, 102 b and 102 c, respectively. The BS 110x may be a pico BS for a pico cell 102 x. The BSs 110 y and 110 z may befemto BSs for the femto cells 102 y and 102 z, respectively. A BS maysupport one or multiple cells. The BSs 110 communicate with userequipment (UEs) 120 a-y (each also individually referred to herein as UE120 or collectively as UEs 120) in the wireless communication network100. The UEs 120 (e.g., 120 x, 120 y, etc.) may be dispersed throughoutthe wireless communication network 100, and each UE 120 may bestationary or mobile.

According to certain aspects, the BSs 110 and UEs 120 may be configuredfor mobility-aware access control as described herein. As shown in FIG.1 , the BS 110 a includes a mobility-aware access control module 112.The mobility-aware access control module 112 may be configured toperform the operations illustrated in one or more of FIGS. 5-15 formobility-aware access control, in accordance with aspects of the presentdisclosure.

The mobility-aware accesscontrol module 122 may be configured to perform the operationsillustrated in one or more of FIGS. 5-15 for mobility-aware accesscontrol, in accordance with aspects of the present disclosure.

Wireless communication network 100 may also include relay stations(e.g., relay station 110 r), also referred to as relays or the like,that receive a transmission of data and/or other information from anupstream station (e.g., a BS 110 a or a UE 120 r) and sends atransmission of the data and/or other information to a downstreamstation (e.g., a UE 120 or a BS 110), or that relays transmissionsbetween UEs 120, to facilitate communication between devices.

A network controller 130 may couple to a set of BSs 110 and providecoordination and control for these BSs 110. The network controller 130may communicate with the BSs 110 via a backhaul. The BSs 110 may alsocommunicate with one another (e.g., directly or indirectly) via wirelessor wireline backhaul.

FIG. 2 illustrates example components of BS 110 a and UE 120 a (e.g., inthe wireless communication network 100 of FIG. 1 ), which may be used toimplement aspects of the present disclosure.

At the BS 110 a, a transmit processor 220 may receive data from a datasource 212 and control information from a controller/processor 240. Thecontrol information may be for the physical broadcast channel (PBCH),physical control format indicator channel (PCFICH), physical hybrid ARQindicator channel (PHICH), physical downlink control channel (PDCCH),group common PDCCH (GC PDCCH), etc. The data may be for the physicaldownlink shared channel (PDSCH), etc. The processor 220 may process(e.g., encode and symbol map) the data and control information to obtaindata symbols and control symbols, respectively. The transmit processor220 may also generate reference symbols, such as for the primarysynchronization signal (PSS), secondary synchronization signal (SSS),and cell-specific reference signal (CRS). A transmit (TX) multiple-inputmultiple-output (MIMO) processor 230 may perform spatial processing(e.g., precoding) on the data symbols, the control symbols, and/or thereference symbols, if applicable, and may provide output symbol streamsto the modulators (MODs) in transceivers 232 a-232 t. Each modulator intransceivers 232 a-232 t may process a respective output symbol stream(e.g., for OFDM, etc.) to obtain an output sample stream. Each modulatormay further process (e.g., convert to analog, amplify, filter, andupconvert) the output sample stream to obtain a downlink signal.Downlink signals from modulators in transceivers 232 a-232 t may betransmitted via the antennas 234 a-234 t, respectively.

At the UE 120 a, the antennas 252 a-252 r may receive the downlinksignals from the BS 110 a and may provide received signals to thedemodulators (DEMODs) in transceivers 254 a-254 r, respectively. Eachdemodulator in transceivers may condition (e.g., filter, amplify,downconvert, and digitize) a respective received signal to obtain inputsamples. Each demodulator may further process the input samples (e.g.,for OFDM, etc.) to obtain received symbols. A MIMO detector 256 mayobtain received symbols from all the demodulators in transceivers 254a-254 r, perform MIMO detection on the received symbols if applicable,and provide detected symbols. A receive processor 258 may process (e.g.,demodulate, deinterleave, and decode) the detected symbols, providedecoded data for the UE 120 a to a data sink 260, and provide decodedcontrol information to a controller/processor 280.

On the uplink, at UE 120 a, a transmit processor 264 may receive andprocess data (e.g., for the physical uplink shared channel (PUSCH)) froma data source 262 and control information (e.g., for the physical uplinkcontrol channel (PUCCH) from the controller/processor 280. The transmitprocessor 264 may also generate reference symbols for a reference signal(e.g., for the sounding reference signal (SRS)). The symbols from thetransmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by the demodulators in transceivers 254a-254 r (e.g., for SC-FDM, etc.), and transmitted to the BS 110 a. Atthe BS 110 a, the uplink signals from the UE 120 a may be received bythe antennas 234, processed by the modulators in transceivers 232 a-232t, detected by a MIMO detector 236 if applicable, and further processedby a receive processor 238 to obtain decoded data and controlinformation sent by the UE 120 a. The receive processor 238 may providethe decoded data to a data sink 239 and the decoded control informationto the controller/processor 240.

The memories 242 and 282 may store data and program codes for BS 110 aand UE 120 a, respectively. A scheduler 244 may schedule UEs for datatransmission on the downlink and/or uplink.

The controller/processor 280 and/or other processors and modules at theUE 120 a may perform or direct the execution of processes for thetechniques described herein. For example, as shown in FIG. 2 , thecontroller/processor 240 of the BS 110 a includes a mobility-awareaccess control module 241 that may be configured to perform theoperations illustrated in one or more of FIGS. 5-15 for mobility-awareaccess control, according to aspects described herein. As shown in FIG.2 , the controller/processor 280 of the UE 120 a includes amobility-aware access control module manager 281 that may be configuredto perform the operations illustrated in one or more of FIGS. 5-15 formobility-aware access control, according to aspects described herein.Although shown at the Controller/Processor, other components of the UE120 a and BS 110 a may be used performing the operations describedherein.

FIG. 3 is a diagram illustrating examples of radio access networks, inaccordance with various aspects of the disclosure.

As shown by reference number 305, a traditional (for example, 3G, 4G,LTE) radio access network may include multiple base stations 310 (forexample, access nodes (AN)), where each base station 310 communicateswith a core network via a wired backhaul link 315, such as a fiberconnection. A base station 310 may communicate with a UE 320 via anaccess link 325, which may be a wireless link. In some aspects, a basestation 310 shown in FIG. 3 may correspond to a base station 110 shownin FIG. 1 . Similarly, a UE 320 shown in FIG. 3 may correspond to a UE120 shown in FIG. 1 .

As shown by reference number 330, a radio access network may include awireless backhaul network. In some aspects or scenarios, a wirelessbackhaul network may sometimes be referred to as an integrated accessand backhaul (IAB) network. An IAB network may include multiple basestations and sometimes the base stations may be of differing types orhave differing operational characteristics. For example, in someaspects, an IAB network may have at least one base station that is ananchor base station 335. The anchor base station may communicates with acore network via a wired backhaul link 340, such as a fiber connection.An anchor base station 335 may also be referred to as an IAB donor.Anchor base stations can be configured to communicate with other typesof base stations or other communication devices (e.g. in a radio networkor IAB network).

The IAB network may also include one or more non-anchor base stations345. Non-anchor base stations may be referred to as relay base stationsor IAB nodes. The non-anchor base station 345 may communicate directlywith or indirectly with (for example, via one or more other non-anchorbase stations 345) the anchor base station 335 via one or more backhaullinks 350 to form a backhaul path to the core network for carryingbackhaul traffic. Backhaul link 350 may be a wireless link. Anchor basestation(s) 335 or non-anchor base station(s) 345 may communicate withone or more UEs 355 via access links 360, which may be wireless linksfor carrying access traffic. In some aspects, an anchor base station 335or a non-anchor base station 345 shown in FIG. 3 may correspond to abase station 110 shown in FIG. 1 . Similarly, a UE 355 shown in FIG. 3may correspond to a UE 120 shown in FIG. 1 .

As shown by reference number 365, in some aspects, a radio accessnetwork that includes an IAB network may utilize a variety of spectrumtypes. For example, an IAB network may utilize a variety of differingradio frequency bands. In a few particular examples and according tosome aspects, millimeter wave technology or directional communicationscan be utilized (for example, beamforming, precoding) for communicationsbetween base stations or UEs (for example, between two base stations,between two UEs, or between a base station and a UE). In additional oralternative aspects or examples, wireless backhaul links 370 betweenbase stations may use millimeter waves to carry information or may bedirected toward a target base station using beamforming, precoding.Similarly, the wireless access links 375 between a UE and a base stationmay use millimeter waves or may be directed toward a target wirelessnode (for example, a UE or a base station). In this way, inter-linkinterference may be reduced.

In some aspects, an IAB network may support a multi-hop network or amulti-hop wireless backhaul. Additionally, or alternatively, each nodeof an IAB network may use the same radio access technology (for example,5G/NR). Additionally, or alternatively, nodes of an IAB network mayshare resources for access links and backhaul links, such as timeresources, frequency resources, spatial resources. Furthermore, variousarchitectures of IAB nodes or IAB donors may be supported.

In some aspects, an IAB donor may include a central unit (CU) thatconfigures IAB nodes that access a core network via the IAB donor andmay include a distributed unit (DU) that schedules and communicates withchild nodes of the IAB donor.

In some aspects, an IAB node may include a mobile termination component(MT) that is scheduled by and communicates with a DU of a parent node,and may include a DU that schedules and communicates with child nodes ofthe IAB node. A DU of an IAB node may perform functions described inconnection with base station 110 for that IAB node, and an MT of an IABnode may perform functions described in connection with UE 120 for thatIAB node.

FIG. 4 is a diagram illustrating an example of an IAB networkarchitecture, in accordance with various aspects of the disclosure. Asshown in FIG. 4 , an IAB network may include an IAB donor 405 thatconnects to a core network via a wired connection (for example, as awireline fiber). For example, an Ng interface of an IAB donor 405 mayterminate at a core network. Additionally, or alternatively, an IABdonor 405 may connect to one or more devices of the core network thatprovide a core access and mobility management function (AMF). In someaspects, an IAB donor 405 may include a base station 110, such as ananchor base station, as described above in connection with FIG. 3 . Asshown, an IAB donor 405 may include a CU, which may perform ANCfunctions or AMF functions. The CU may configure a DU of the IAB donor405 or may configure one or more IAB nodes 410 (for example, an MT or aDU of an IAB node 410) that connect to the core network via the IABdonor 405. Thus, a CU of an IAB donor 405 may control or configure theentire IAB network that connects to the core network via the IAB donor405, such as by using control messages or configuration messages (forexample, a radio resource control (RRC) configuration message, an F1application protocol (F1AP) message).

As described above, the IAB network may include IAB nodes 410 (shown asIAB nodes 1 through 4) that connect to the core network via the IABdonor 405. As shown, an IAB node 410 may include an MT and may include aDU. The MT of an IAB node 410 (for example, a child node) may becontrolled or scheduled by another IAB node 410 (for example, a parentnode) or by an IAB donor 405. The DU of an IAB node 410 (for example, aparent node) may control or schedule other IAB nodes 410 (for example,child nodes of the parent node) or UEs 120. Thus, a DU may be referredto as a scheduling node or a scheduling component, and an MT may bereferred to as a scheduled node or a scheduled component. In someaspects, an IAB donor 405 may include a DU and not an MT. That is, anIAB donor 405 may configure, control, or schedule communications of IABnodes 410 or UEs 120. A UE 120 may include only an MT, and not a DU.That is, communications of a UE 120 may be controlled or scheduled by anIAB donor 405 or an IAB node 410 (for example, a parent node of the UE120).

According to some aspects, certain nodes may be configured toparticipate in control/scheduling processes. For example in someaspects, when a first node controls or schedules communications for asecond node (for example, when the first node provides DU functions forthe second node’s MT), the first node may be referred to as a parentnode of the second node, and the second node may be referred to as achild node of the first node. A child node of the second node may bereferred to as a grandchild node of the first node. Thus, a DU of aparent node may control or schedule communications for child nodes ofthe parent node. A parent node may be an IAB donor 405 or an IAB node410, and a child node may be an IAB node 410 or a UE 120. Communicationsof an MT of a child node may be controlled or scheduled by a parent nodeof the child node.

As further shown in FIG. 4 , a link between a UE 120 and an IAB donor405, or between a UE 120 and an IAB node 410, may be referred to as anaccess link 415. Each access link 415 may be a wireless access link thatprovides a UE 120 with radio access to a core network via the IAB donor405, and potentially via one or more IAB nodes 410.

As further shown in FIG. 4 , a link between an IAB donor 405 and an IABnode 410, or between two IAB nodes 410, may be referred to as a backhaullink 420. Each backhaul link 420 may be a wireless backhaul link thatprovides an IAB node 410 with radio access to a core network via the IABdonor 405, and potentially via one or more other intermediate IAB nodes410. In some aspects, a backhaul link 420 may be a primary backhaul linkor a secondary backhaul link (for example, a backup backhaul link). Insome aspects, a secondary backhaul link may be used if a primarybackhaul link fails, becomes congested, or becomes overloaded. In an IABnetwork, network resources for wireless communications (for example,time resources, frequency resources, spatial resources) may be sharedbetween access links 415 and backhaul links 420.

As described above, in a typical IAB network, IAB nodes (for example,non-anchor base stations) are stationary (that is, non-moving).Conversely, in a mobile IAB network, some of the IAB nodes may havemobility (that is, may move around in the IAB network). Such IAB nodesmay be referred to as mobile IAB nodes. For example, an IAB node may beinstalled on a vehicle (for example, a bus, a train, a taxi). In amobile IAB network, there may be a mix of stationary and mobile IABnodes. In some cases, the mobile IAB nodes may be constrained to be“leaf” nodes in the mobile IAB network. That is, a mobile IAB node maybe permitted to be only a last-hop IAB node, with only child access UEsconnected to the mobile IAB node. In some other cases, a mobile IAB nodealso may be permitted to have another IAB node as a child node.

In some examples, a mobile IAB node may provide an independently movingcell site. In such a case, a moving cell site (for example, a vehicle,such as a bus, a train, a taxi) can be used for the IAB node to servesurrounding UEs (for example, in an urban area). Here, the mobile IABnode may move relatively randomly, at relatively low speeds (forexample, urban city speed), and over a relatively large distance. Inthis case, the mobility of a given UE (that is not carried with thevehicle) is independent of the mobility of the IAB node (that is, themovement of the UE is not predictable based on the movement of themobile IAB node), but may also be at relatively low speeds (a speedsimilar to the mobile IAB node).

In some other examples, a mobile IAB node may provide a jointly movingcell site (for example, a high-speed train). In such a case, a mobileIAB node may be mounted on the moving cell site (for example, on top ofa high-speed train) in order to serve UEs on or in the moving cell site(for example, UEs inside the high-speed train). Here, the mobility ofthe mobile IAB node may be predictable, at relatively high speeds, andover a large distance. In this use case, UEs on or in the moving cellsite move jointly with the mobile IAB node (that is, UE movement ispredictable based on the movement of the mobile IAB node).

In some other examples, a mobile IAB node may facilitate a platoon,when, for example, a loose group of UEs is generally moving together. Insuch a case, a single IAB node may provide network connectivity fornearby UEs. For example, a mobile IAB node mounted on a first vehicledriving on a freeway may provide network connectivity for UEs in thefirst vehicle as well as for UEs in other vehicles driving on thefreeway in the same direction and at a similar speed. In such cases, themobile IAB node connects to the network, while other vehicles mighthouse respective child nodes. Here, the mobile IAB node moves with localpredictability, at a relatively constant speed, and over a relativelylarge distance. Further, the UEs move jointly with the mobile IAB node.

A mobility state of a communication device or node (e.g., an IAB node)may be defined by a number of characteristics. Generally, a mobilitystate may refer to a node’s mobility class, movement degree, and/ormovement capability. A node’s mobility state may be static (e.g., notchanging) or dynamic (e.g., changing with time). Mobility states may bedependent upon other factors such that it indicates a relative statewith respect to other network nodes.

Mobility states may be based on one or more characteristics as desiredor according to design/operational principles. A first characteristicmay include a level of mobility (for example, stationary, low-speedmobility, medium-speed mobility, high-speed mobility). Mobility levelsmay generally reflect a point in time velocity, a range of velocities, arunning average historical mobility/velocity pattern, or some othercharacterization of general movement abilities. A second characteristicmay include a change or a transition from one mobility state to another(e.g., the mobility state of an IAB node may change or transition overtime). For example, a mobile IAB node may transition to stationary(e.g., from low-speed mobility), or may transition from one mobilityclass to another (e.g., from medium-speed mobility to high-speedmobility). In some instances, a timer may be associated with such atransition (e.g., an IAB node may transition from one state to anotherwithin an indicated window of time). Mobility-state characteristics mayalso generally be shared by a device or among devices for enhancednetwork operations (e.g., using a variety of signals/messages overvarious interfaces).

In some cases, the mobility state of a given IAB node may impactoperation of the mobile IAB network. For example, the performance of anumber of IAB network-related operations may depend on the mobilitystate of a mobile IAB node. Such IAB network-related operations mayinclude, for example, initial cell access, cell selection/reselection,and cell handover. For example, given the mobility state of a mobile IABnode/cell, the mobile IAB node may or may not be the best choice for aserving cell of a user equipment (UE) or a mobile termination component(MT). For example, serving cell choices may typically be based on signalquality measurements, which may be affected by mobility. Thus, at afirst instance in time, the mobile IAB node may have a good signalquality, leading to a UE/MT selecting the mobile IAB to camp on.However, given the mobility of the mobile IAB node, the IAB node mayhave a poor signal quality at a second instance in time shortly afterthe first instance. Thus, in this case, the mobile IAB node may not bethe best choice as a serving cell for the UE/MT. Accordingly, knowledgeof the mobility state of a given IAB node may be desirable to facilitatethe cell selection/access/handover operations described above forefficient and acceptable performance of the mobile IAB network.

Example Mobility-Aware Access Control

Aspects of the present disclosure provide techniques for mobility-awareaccess control. For example, as noted above, in some cases, it may bedesirable to consider mobility state information of an IAB node ininitial access, cell selection/reselection, and handover procedures toavoid situations where the IAB node may not be suitable as a servingcell due to mobility of the IAB node. However, based on whether (andwhere) the required mobility state information is available, there maybe different options for implementing mobility-aware access control, asdescribed herein.

For example, a first option may involve a centralized solutionimplemented by a network node, such as a control unit (CU) of an IABnode (e.g., IAB donor 405). According to this option, the network nodemay control cell (re)selection and/or handovers of a wireless devicebased on mobility state information, which may be transparent to thewireless device. For example, a wireless device (e.g., UE 120 and/or anMT of an IAB node 410) may follow a typical power/quality-based cell(re)selection procedure to select a target cell (e.g., IAB node 410) tocamp on. However, in certain cases, the target cell may not be asuitable serving cell for the wireless device due to mobility of thetarget cell (e.g., the target cell is moving at a high-speed, in adifferent direction than the wireless device, etc.), which the UE maynot have knowledge of. Thus, in this case, when the wireless deviceselects a target cell that may not be suitable for the wireless device(e.g., due to a mobility state of the target cell), the network node mayinstruct the wireless device to hand over to a more suitable cell.Similarly, for a connected wireless device, the target cell to hand overto may be selected based on a mobility state associated with the targetcell.

FIG. 5 is a flow diagram illustrating example operations 500 forwireless communication in a network, in accordance with certain aspectsof the present disclosure. The operations 500 may be performed, forexample, by a network node, such as a control unit (CU) in a IAB node(e.g., IAB donor 405). Operations 500 may be implemented as softwarecomponents that are executed and run on one or more processors (e.g.,controller/processor 240 of FIG. 2 ). Further, the transmission andreception of signals by the network node in operations 500 may beenabled, for example, by one or more antennas (e.g., antennas 234 ofFIG. 2 ). In certain aspects, the transmission and/or reception ofsignals by the network may be implemented via a bus interface of one ormore processors (e.g., controller/processor 240) obtaining and/oroutputting signals.

The operations 500 may begin, at 505, by obtaining at least one of firstmobility state information corresponding to a first cell in the network,second mobility state information corresponding to a second cell in thenetwork, or third mobility state information corresponding to a wirelessdevice in the network.

At 510, the network node receive a measurement report from the wirelessdevice, wherein the measurement report includes measurement informationassociated with the second cell.

At 515, the network node determines whether to initiate a handoverprocedure to hand over the wireless device from the first cell to thesecond cell based at least in part on at least one of the first mobilitystate information, the second mobility state information, or the thirdmobility state information.

At 520, the network node takes one or more actions based on thedetermination.

As noted above, under a centralized approach to mobility-aware accesscontrol, a network node may control cell (re)selection and/or handoversof a wireless device based on mobility state information.

FIG. 6 illustrates a detailed call-flow diagram of centralizedmobility-aware access control techniques, according to certain aspectspresented herein. Though call-flow or operational descriptions hereinmay be described as certain actions as steps, the described actions orsteps may be preferred in variety of arrangements or orders. Byproviding example logical descriptions, those of skill in the art willunderstand various permutations are achievable and possible.

For example, as illustrated in FIG. 6 , at steps 1 a and 1 b, a networknode 602, such as a CU (which may be part of the first cell), may obtainfirst mobility state information corresponding to a first cell 604 andsecond mobility state information corresponding to a second cell 606. Incertain cases, obtaining the first mobility state information mayinclude inferring the first mobility state information based, at leastin part, on prior measurement information or prior location informationassociated with the first cell 604. Similarly, in some cases, obtainingthe second mobility state information may include inferring the secondmobility state information based, at least in part, on prior measurementinformation or prior location information associated with the secondcell 606. For example, in some cases, based on prior measurement and/orlocation information of the first cell 604 and/or second cell 606, thenetwork node 602 may be able to infer whether the first cell 604 and/orsecond cell 606 are relatively static or not, for example, in relationto a wireless device, such as the UE/MT 608. For example, in some cases,the network node 602 may be able to infer whether the first cell 604and/or second cell 606 cell are moving, or not moving, in a samedirection as the UE/MT 608 based on the prior measurement informationand/or location information of the first cell 604 and/or second cell606. In some cases, the network node 602 may receive an explicitindication from the first cell 604 and/or the second cell 606,indicating the first mobility state information and/or the secondmobility state information.

According to aspects, the mobility state information may provide anindication of a level of mobility corresponding to the wireless devicefrom which it was received (e.g., the first cell 604, the second cell606, or the UE/MT 608). For example, the level of mobility may compriseone of stationary mobility, low-speed mobility, medium-speed mobility,or high-speed mobility. Additionally, in some cases, the mobility stateinformation may provide an indication of a change or transition from onemobility state to another corresponding to the wireless device fromwhich it was received (e.g., the first cell 604, the second cell 606, orthe UE/MT 608). For example, in some case, the indication of the changeor transmission may indicate that the first cell 604 is changing from ahigh-speed mobility to a stationary mobility, or the like.

At step 2, the UE/MT 608 may perform an access procedure and establish aconnection with the first cell 604.

Thereafter, at step 3, the network node 602 may obtain third mobilitystate information corresponding to the UE/MT 608. In some cases, thenetwork node 602 may receive signaling from the UE/MT 608 indicating thethird mobility state information corresponding to the UE/MT 608. Inother cases, the network node 602 may obtain the third mobility stateinformation by inferring the third mobility state information based, atleast in part, on prior measurement information or prior locationinformation associated with the UE/MT 608 (e.g., similar to inferringwith respect to the first cell 604/second cell 606, described above).

At step 4, while camping on the first cell 604, the UE/MT 608 may comein range of a neighboring cell, such as the second cell 606, and performmeasurements on one or more signals (e.g., reference signals) receivedfrom the second cell 606.

At step 5, the network node 602 may receive a measurement report fromthe UE/MT 608 that includes measurement information associated with thesecond cell 606. For example, in some cases, the measurement report mayinclude measurement information taken based on the one or more signalsreceived at the UE/MT 608 from the second cell 606.

At step 6, the network node 602 may determine whether to initiate ahandover procedure to hand over the UE/MT 608 from the first cell 604 tothe second cell 606 based at least in part on at least one of the firstmobility state information, the second mobility state information, orthe third mobility state information. In some cases, determining whetherto initiate the handover procedure may include determining, based on atleast one of the first mobility state information or the third mobilitystate information, that the first cell 604 is not suitable for the UE/MT608. For example, in some cases, the network node may determine that thefirst cell 604 may not be suitable as a serving cell for the UE/MT608due to mobility of either the first cell 604 or the UE/MT 608 (e.g.,the first cell 604 and UE/MT 608are moving in different directions,etc.).

Accordingly, at step 7, based on the determination in step 6, thenetwork node 602 may take one or more actions. For example, in somecases, taking the one or more actions may include determining toinitiate the handover procedure to hand over the UE/MT 608 from thefirst cell 604 to the second cell 606 based on the determination thatthe first cell 604 is not suitable for the UE/MT 608. In this cases, asillustrated at step 7, the network node 602 may transmit a handovercommand to the UE/MT 608 and the second cell 606, instructing the UE/MT608to hand over to the second cell 606 from the first cell 604.

Thereafter, at step 8, based on the handover command, the UE/MT 608 mayperform an access procedure and establish a connection with the secondcell 606.

Another option for mobility-aware access control may involve adistributed approach where a first wireless device (e.g., a targetserving cell) and a second wireless device (e.g., UE/MT) may have therequired mobility state information to suitably control their own access(e.g., as opposed to the centralized approach above where the targetserving cell/UE/MT do not have the mobility state information and needthe CU to assist in access/handover). For example, a distributedapproach to mobility-aware access control may involve the UE/MT andtarget serving cell autonomously determining cell (re)selection/handoverdecisions based on known mobility state information.

FIG. 7 is a flow diagram illustrating example operations 700 forwireless communication in a network. These can include, for example,mobility-aware access control for cell (re)selection and/or handover, inaccordance with certain aspects of the present disclosure. Theoperations 700 may be performed, for example, by a first wirelessdevice, such as a target serving cell (e.g., IAB donor 405 and/or IABnode 410), a user equipment (e.g., UE 120), and/or a mobile terminationcomponent (MT) of an IAB node 410. Operations 700 may be implemented assoftware components that are executed and run on one or more processors(e.g., controller/processor 240 or controller/processor 280 of FIG. 2 ).Further, the transmission and reception of signals by the network nodein operations 700 may be enabled, for example, by one or more antennas(e.g., antennas 234, 252 of FIG. 2 ). In certain aspects, thetransmission and/or reception of signals by the network may beimplemented via a bus interface of one or more processors (e.g.,controller/processor 240 or controller/processor 280) obtaining and/oroutputting signals.

The operations 700 may begin, at 705, by receiving one or more signalsfrom a second wireless device in the network, wherein the one or moresignals provide an indication of a mobility state corresponding to thesecond wireless device.

At 710, the first wireless device determines whether to establish aconnection with the second wireless device based, at least in part, onthe indication of the mobility state corresponding to the secondwireless device.

At 715, the first wireless device takes one or more actions based on thedetermination.

As noted above, the distributed approach to mobility-aware accesscontrol may involve the UE/MT and target serving cell autonomouslydetermining cell (re)selection/handover decisions based on knownmobility state information.

For example, FIG. 8 is a call flow diagram illustrating exampleoperations performed by a first wireless device 802, such as a UE 120and/or MT of an IAB node 410, for mobility-aware access control for cell(re)selection. As illustrated, at step 1, the first wireless device 802may receive one or more signals from a second wireless device 804, suchas a target serving cell. In some cases, the target serving cell may bean MT of an IAB node 410 (e.g., assuming the first wireless device is aUE) or an IAB donor 405 (e.g., assuming the first wireless device is anMT of an IAB node 410).

Signals communicated in a network may take on a number of forms and forvarious purposes. For example, additionally, in some cases, the one ormore signals may comprise at least one of a synchronization signal block(SSB), a physical broadcast channel (PBCH) signal, a remaining systeminformation (RMSI) signal, or a random access channel (RACH) message 2or RACH message 4. According to aspects, the one or more signals mayprovide an indication of a mobility state corresponding to the secondwireless device 804. In some cases, the indication may be implicit orexplicit. For example, in some cases, one or more resources used totransmit the one or more signals may implicitly indicate a mobilitystate corresponding to the second wireless device 804. For example, insome cases, a first type of resource used to transmit the one or moresignals may correspond to a first mobility state or indicate atransition between mobility states while a second type of resource usedto transmit the one or more signals may correspond to a second mobilitystate or indicate a different transition between mobility states.Additionally, in some cases, the mobility state may be an explicitindication included in the one or more signals. For example, in somecases, the second wireless device may provide an explicit indication ofits mobility state in a RACH message 2 or RACH message 4. In eithercase, the first wireless device 802 may receive the one or more signalsand determine the mobility state corresponding to the second wirelessdevice 804.

At step 2 illustrated in FIG. 8 , the first wireless device 802 maydetermine whether to establish the connection with the second wirelessdevice 804. A determination of this nature may be based, at least inpart or in whole, on the mobility state corresponding to the secondwireless device 804. In some cases, this determination may be based onone or more cell selection criteria related to the mobility statecorresponding to the second wireless device 804. For example, in somecases, the one or more cell selection criteria may, for example, specifythat the first wireless device 802 may only select the second wirelessdevice 804 if the second wireless device 804 has a specific mobilitystate, is moving in a same direction with a similar mobility state asthe first wireless device 802, or the like. According to aspects, insome cases, the one or more cell selection criteria may be specified ina standards document and/or pre-programmed in the first wireless device802.

According to aspects, determining whether to establish the connectionwith the second wireless device 804 may include determining to establishthe connection with the second wireless device 804 when, based on theindication of the mobility state corresponding to the second wirelessdevice 804, the one or more cell selection criteria are satisfied. Forexample, in some cases, if the one or more criteria specify that thesecond wireless device 804 must have a high-moving mobility state andthe determined mobility state of the second wireless device 804satisfies this high-moving mobility state criteria (or any othercriteria related to mobility state), then the first wireless device 802may determine to establish the connection with the second wirelessdevice 804.

According to aspects, if the first wireless device 802 determines toestablish the connection with the second wireless device 804, then, atstep 3 in FIG. 8 , the first wireless device 802 may take one or moreactions based on the determination. For example, as illustrated, at step3, based on the determination, the first wireless device 802 may performan access procedure and establish a connection with the second wirelessdevice 804.

Yet in some cases, determining whether to establish the connection withthe second wireless device 804 can be based on or depend on a number offactors. These may include, for example, determining not to establishthe connection with the second wireless device 804 when, based on theindication of the mobility state corresponding to the second wirelessdevice 804, the one or more cell selection criteria are not satisfied.For example, in some cases, if the one or more criteria specify that thesecond wireless device 804 must have a high-moving mobility state andthe determined mobility state of the second wireless device 804 does notsatisfy this high-moving mobility state criteria (or any other criteriarelated to mobility state), then the first wireless device 802 maydetermine not to establish the connection with the second wirelessdevice 804. Thus, in this case, at step 3, while not illustrated, thefirst wireless device 802 may take one or more actions, such assearching for and selecting a different, more-suitable second wirelessdevice.

As noted above, in some cases, the first wireless device 802 maydetermine (or may infer) the mobility state of a second wireless device804 based on a set of measurements or location information. In othercases, the first wireless device 802 may instead determine or infer itsown mobility state with respect to the second wireless node 804 based ona set of measurements or location information. For example, in somecases, the first wireless device 802 may determine whether the firstwireless device 802 has low mobility (e.g., is relatively static) orhigh mobility with respect to the second wireless device 804, and ifhigh mobility, whether the first wireless device 802 is moving towardsor away from second wireless node 804.

According to aspects, after the first wireless device 802 determines themobility state of the second wireless device 804/first wireless device802, this mobility state information may be used for various purposessuch as reporting to another node (e.g. a network node or the secondwireless device 804), choosing the second wireless device 804 toestablish a connection with, or handing over to or from the secondwireless device 804, as discussed above.

In some cases, as noted above, the first wireless device may be a UE (orIAB-node MT) and may measure a signal metric, such as signal strength(e.g. reference signal received power (RSRP)), of the second wirelessdevice (e.g., a cell). The first wireless device may also determinevariations in certain signal metrics over a period of time, such asvariations of RSRP, Doppler, RTT, and the like. The first wirelessdevice may then decide whether to camp on the cell based, at least inpart, on these two factors (e.g., the RSRP and the variation in thesignal metrics). For example, the first wireless device may performmeasurements on two cells. For example, the first wireless device maydetermine that a first cell has an RSRP value of X and a variation of Y.Additionally, the first wireless device may determine that a second cellhas an RSRP value X+3 dB and a variation 10Y. In this case, the firstwireless device may select and camp on the first cell. For example, eventhough the first wireless device determines that the second cell has astronger RSRP (and would traditionally be selected due to the strongerRSRP), based on the variation in the signal metrics of the second cell,the first wireless device may infer that the connection to the secondwireless device may not be reliable or suitable since the signal metricsof the second wireless device varies significantly (presumable due tohigher relative mobility to the second wireless device). Hence, thefirst wireless device may instead select the first wireless device withthe weaker RSRP but with a more reliable/predictable connection (e.g.,low variation).

FIG. 9 is a call flow diagram illustrating example operations performedby a first wireless device, such as a target cell (e.g., an MT of an IABnode 410 or a IAB donor 405), for mobility-aware access control for cell(re)selection.

As illustrated, at step 1, a first wireless device 902 may receive oneor more signals from a second wireless device 904, such as a UE 120 orMT of an IAB node 410. In some cases, the one or more signals compriseat least one of a random access channel (RACH) message 1 or RACH message3. Further, in some cases, the one or more signals may provide anindication of a mobility state corresponding to the second wirelessdevice 904. As noted above, the indication of the mobility statecorresponding to the second wireless device 904 may be providedimplicitly or explicitly. For example, in some cases, a RACH preamble IDof the RACH message 1 or resources used to transmit the RACH message 1may implicitly provide the indication of the mobility statecorresponding to the second wireless device 904. Additionally, as noted,in some cases, the indication of the mobility state corresponding to thesecond wireless device 904 may be provided explicitly, for example, inthe RACH message 1 or RACH message 3 from the second wireless device904.

At step 2 illustrated in FIG. 9 , the first wireless device 902 maydetermine whether to establish the connection with the second wirelessdevice 904. A determination of this nature may be based, at last in partor in whole, on the mobility state corresponding to the second wirelessdevice 904. In some cases, this determination may also be based on oneor more cell selection criteria related to the mobility statecorresponding to the second wireless device 904, similar to step 2 inFIG. 8 .

Further, in some cases, determining whether to establish the connectionwith the second wireless device 904 may include performingprioritization based on the indication of the mobility state of secondwireless device 904. For example, the example of FIG. 9 focuses on (1)the second wireless device 904 (e.g., UE/MT) indicating its mobilitystate in one or more signals, such as RACH MSG1 or 3, and (2) the firstwireless device 902 (e.g., a target cell) performing prioritizationbased on the mobility state of the second wireless device 904. Accordingto aspects, “prioritization” may be related to a cell “detection” phase.For example, assume the mobility state is indicated by the secondwireless device 904 via RACH MSG1. The first wireless device 902 mayimplement a RACH receiver algorithm to detect any UE/MTs (e.g., secondwireless devices 904) sending a RACH MSG1. The implementation of thisalgorithm and/or the RACH MSG1 configuration may prioritize detectingone class versus the other, for example, by allocating more resources toone class, or by searching for RCAH MSG1 of one class more extensively(e.g. more frequently, or using a beamforming (BF) configuration thatachieves higher BF gain). Additionally, in some cases, “prioritization”may be related to the cell “selection” phase. That is, after detectingone or multiple second wireless devices 904 (e.g., UEs/MTs), the firstwireless device 902 may decide which second wireless device to select toestablish a connection and which second wireless device to reject, orwhich second wireless device to attempt to establish a connection withfirst.

Thereafter, according to aspects, determining, by the first wirelessdevice 902, whether to establish the connection with the second wirelessdevice may include one of determining to establish the connection withthe second wireless device 904 based on the prioritization ordetermining not to establish the connection with the second wirelessdevice 904 based on the prioritization.

According to aspects, if the first wireless device 902 determines toestablish the connection with the second wireless device 904, then, atstep 3 in FIG. 9 , the first wireless device 902 may take one or moreactions based on the determination. For example, as illustrated, at step3, based on the determination, the first wireless device 902 may performan access procedure and establish a connection with the second wirelessdevice 904. However, if the first wireless device 902 determines not toestablish the connection with the second wireless device 904, then, atstep 3, the first wireless device 902 may take one or more actions, suchas informing the second wireless device 904 that a connection will notbe established.

FIG. 10 is a flow diagram illustrating example operations 1000 forwireless communication in a network, for example, for mobility-awareaccess control for cell hand over, in accordance with certain aspects ofthe present disclosure. The operations 1000 may be performed, forexample, by a first wireless device, such as a user equipment (e.g., UE120) and/or a mobile termination component (MT) of an IAB node 410.Operations 1000 may be implemented as software components that areexecuted and run on one or more processors (e.g., controller/processor240 or controller/processor 280 of FIG. 2 ). Further, the transmissionand reception of signals by the network node in operations 1000 may beenabled, for example, by one or more antennas (e.g., antennas 234, 252of FIG. 2 ). In certain aspects, the transmission and/or reception ofsignals by the network may be implemented via a bus interface of one ormore processors (e.g., controller/processor 240 or controller/processor280) obtaining and/or outputting signals.

The operations 1000 may begin, at 1005, by camping on a first cell inthe network.

At 1010, the first wireless device receives one or more signals from asecond cell in the network.

At 1015, the first wireless device determining mobility stateinformation corresponding to the second cell in the network based atleast in part on the one or more signals.

At 1020, the first wireless device transmits a measurement report to anetwork node based, at least in part, on the one or more signals fromthe second cell and the mobility state information corresponding to thesecond cell.

FIG. 11 is a flow diagram illustrating example operations 1100 forwireless communication in a network, for example, for mobility-awareaccess control for cell hand over, in accordance with certain aspects ofthe present disclosure. The operations 1100 may be performed, forexample, by a network node, such as CU of an IAB donor 405. Operations1100 may be considered complimentary to operations 1000 performed by aUE 120 and/or MT of an IAB node 410.

Operations 1100 may be implemented as software components that areexecuted and run on one or more processors (e.g., controller/processor240). Further, the transmission and reception of signals by the networknode in operations 1100 may be enabled, for example, by one or moreantennas (e.g., antennas 234 of FIG. 2 ). In certain aspects, thetransmission and/or reception of signals by the network may beimplemented via a bus interface of one or more processors (e.g.,controller/processor 240) obtaining and/or outputting signals.

The operations 1100 may begin, at 1105, by receiving a measurementreport from a wireless device that is camping on a first cell in thenetwork, wherein the measurement report is based on one or more signalsfrom a second cell in the network.

At 1110, the network node determines whether to initiate a handoverprocedure to hand the wireless device over to second cell based, atleast in part, on mobility state information corresponding to the secondcell.

At 1115, the network node takes one or more actions based on thedetermination.

FIG. 12 is a call flow diagram illustrating example operations formobility-aware access control for cell handover, in accordance withcertain aspects of the present disclosure. The example operationsillustrated in FIG. 12 provide a more-detailed illustration ofoperations 1000 and operations 1100 illustrated in FIG. 10 and FIG. 11 ,respectively.

As illustrated, at step 1 in FIG. 12 , a first wireless device 1202(e.g., UE 120 and/or MT of an IAB node 410) may establish a connectionand camp on a first cell 1204.

At step 2, the connected first wireless device 1202 may have (oracquire) information about a mobility state of a neighboring cell, suchas the second cell 1206. For example, in some cases, at step 2, thefirst wireless device 1202 may receive one or more signals from a secondcell 1206. According to aspects, the first wireless device 1202 mayperform one or more measurements on the one or more signals receivedfrom the second cell 1206. As noted above, in some cases, the one ormore signals may comprise at least one of a synchronization signal block(SSB), a physical broadcast channel (PBCH) signal, a remaining systeminformation (RMSI) signal.

Additionally, the first wireless device 1202 may determine a mobilitystate corresponding to the second cell 1206 based on the one or moresignals received from the second cell 1206. For example, in some cases,the one or more signals may provide an indication of mobility stateinformation corresponding to the second cell 1206 in the network. Inthis case, the first wireless device 1202 may determine the mobilitystate information based at least in part on the indication of themobility state information corresponding to the second cell 1206 in thenetwork.

At step 3, the first wireless device 1202 may transmit a measurementreport to a network node 1208 based, at least in part, on the one ormore signals from the second cell 1206 and the mobility stateinformation corresponding to the second cell 1206. In some cases, asillustrated, the network node 1208 may be a CU, which, in some cases,may be part of the first cell 1204. In some cases, the measurementreport includes an indication of the determined mobility statecorresponding to the second cell 1206.

Additionally, in some cases, the first wireless device 1202 maydetermine whether to transmit the measurement report based on atriggering event. In some cases, the triggering event may be based onthe mobility state information corresponding to the second cell 1206. Inother words, the first wireless device 1202 may determine whether totransmit a measurement report to the network node 1208 corresponding tothe second cell 1206 based on the mobility state corresponding to thesecond cell 1206 (e.g., and whether the mobility state corresponding tothe second cell meets the triggering event). For example, in some cases,if the first wireless device 1202 determines that the mobility statecorresponding to the second cell 1206 meets the triggering event (e.g.,a mobility state of the second cell 1206 is “mobile” and a measured RSRPof the second cell 1206 is greater than a threshold RSRP), the firstwireless device 1202 may decide to transmit the measurement report tothe network node 1208. However, if the first wireless device 1202determines that the mobility state corresponding to the second cell 1206does not meet a triggering event, the first wireless device 1202 maydecide not to transmit the measurement report to the network node 1208.According to aspects, determining whether to transmit a measurementreport based on mobility state information corresponding to the secondcell 1206 may allow the first wireless device 1202 to conserve time andenergy by not having to report measurements for cells that are notsuitable (e.g., cells that do not meet the triggering event).

From the perspective of the network node 1208 (e.g., CU), at step 3, thenetwork node 1208 may receive the measurement report from the firstwireless device 1202 that is camping on a first cell 1204 in thenetwork. As noted, the measurement report may be based (and carryinformation regarding measurements for) on one or more signals from asecond cell 1206 in the network. Additionally, in some cases, thenetwork node 1208 may receive an indication of mobility stateinformation corresponding to the second cell 1206 from the firstwireless device 1202. In some cases, the mobility state informationcorresponding to the second cell 1206 is received in the measurementreport.

At step 4, after receiving the measurement report from the firstwireless device 1202, the network node 1208 may determine whether toinitiate a handover procedure to hand the first wireless device 1202over to the second cell 1206 based, at least in part, on mobility stateinformation corresponding to the second cell 1206. In some cases,determining whether to initiate a handover procedure to hand the firstwireless device 1202 over to second cell 1206 may be based, at least inpart, on one or more conditions related to the mobility statecorresponding to the second cell 1206, for example, as discussed above.Further, according to aspects, determining whether to initiate thehandover procedure may involve determining to initiate the handoverprocedure when, for example, the mobility state informationcorresponding to the second cell 1206 satisfies the one or moreconditions. Similarly, determining whether to initiate the handoverprocedure may involve determining not to initiate the handover procedurewhen, for example, the mobility state information corresponding to thesecond cell 1206 does not satisfy the one or more conditions.

According to aspects, at step 5, the network node 1208 may take one ormore actions based on the determination of whether to initiate thehandover procedure. For example, if the network node 1208 determines toinitiate the handover procedure, the network node 1208 may, asillustrated, transmit a handover command to hand over the first wirelessdevice 1202 to the second cell 1206 in the network. According toaspects, the handover command may be transmitted to at least one of thefirst wireless device 1202 or the second cell 1206.

Thus, at step 5, the first wireless device 1202 may receive a handovercommand to hand over to the second cell 1206 in the network based, atleast in part, on at least one of the measurement report or the mobilitystate information corresponding to the second cell 1206.

Thereafter, at step 6, the first wireless device 1202 may take one ormore actions based on the handover command. For example, as illustratedat step 6, the first wireless device 1202 may perform an accessprocedure and establish a connection with the second cell 1206.According to aspects, if the network node 1208 decides not to initiatethe handover procedure and the first wireless device 1202 does notreceive a handover command, the first wireless device 1202 may beginsearching for other suitable neighbor cells to handover to, repeatingthe operations illustrated in FIG. 12 .

In some cases, a handover command may be conditional. For example, insome cases, instead of the first wireless device providing the networknode a measurement report, in some cases, the network node may providethe first wireless device with a conditional handover command thatallows the first wireless device to initiate a handover when certainconditions are satisfied. For example, in some cases, the conditionalhandover command may include one or more conditions related to amobility state corresponding to a second cell that the first wirelessdevice wants to be handed over to. According to aspects, if the mobilitystate corresponding to the second cell satisfies one or more of theconditions in the conditional handover command, the first wirelessdevice may initiate a handover to the second cell.

FIG. 13 is a flow diagram illustrating example operations 1300 forwireless communication in a network, for example, for mobility-awareaccess control for cell hand over according to a conditional handovercommand, in accordance with certain aspects of the present disclosure.The operations 1300 may be performed, for example, by a first wirelessdevice, such as a user equipment (e.g., UE 120) and/or a mobiletermination component (MT) of an IAB node 410. Operations 1300 may beimplemented as software components that are executed and run on one ormore processors (e.g., controller/processor 240 or controller/processor280 of FIG. 2 ). Further, the transmission and reception of signals bythe network node in operations 1300 may be enabled, for example, by oneor more antennas (e.g., antennas 234, 252 of FIG. 2 ). In certainaspects, the transmission and/or reception of signals by the network maybe implemented via a bus interface of one or more processors (e.g.,controller/processor 240 or controller/processor 280) obtaining and/oroutputting signals.

The operations 1300 may begin, at 1305, by camping on a first cell inthe network.

At 1310, the first wireless device receives a conditional handovercommand from a network node in the network to hand over to a second cellin the network, wherein the conditional handover command includes one ormore conditions based, at least in part, on a mobility statecorresponding to the second cell.

At 1315, the first wireless device takes one or more actions based, atleast in part, on the conditional handover command.

FIG. 14 is a flow diagram illustrating example operations 1400 forwireless communication in a network, for example, for mobility-awareaccess control for cell hand over according to a conditional handovercommand, in accordance with certain aspects of the present disclosure.The operations 1400 may be performed, for example, by a network node,such as CU of a IAB donor 405. Operations 1400 may be consideredcomplimentary to operations 1300 performed by a UE 120 and/or MT of anIAB node 410.

Operations 1400 may be implemented as software components that areexecuted and run on one or more processors (e.g., controller/processor240). Further, the transmission and reception of signals by the networknode in operations 1400 may be enabled, for example, by one or moreantennas (e.g., antennas 234 of FIG. 2 ). In certain aspects, thetransmission and/or reception of signals by the network may beimplemented via a bus interface of one or more processors (e.g.,controller/processor 240) obtaining and/or outputting signals.

The operations 1400 may begin, at 1405, by communicating with a wirelessdevice in the network that is camping on a first cell in the network.

At 1110, the network node transmits a conditional handover command froma network node in the network to hand over to a second cell in thenetwork, wherein the conditional handover command includes one or moreconditions based, at least in part, on a mobility state corresponding tothe second network.

FIG. 15 is a call flow diagram illustrating example operations formobility-aware access control for cell handover according to aconditional handover command. The example operations illustrated in FIG.15 provide a more-detailed illustration of operations 1300 andoperations 1400 illustrated in FIG. 13 and FIG. 14 , respectively.

As illustrated, at step 1 if FIG. 15 , a first wireless device 1502(e.g., UE 120 and/or MT of an IAB node 410) may establish a connectionand camp on a first cell 1504.

At step 2, the first wireless device 1502 may receive, from a networknode 1508 in the network, such as a CU, a conditional handover commandto hand over to a second cell 1506 in the network. In some cases, theconditional handover command includes one or more conditions that arebased, at least in part, on a mobility state corresponding to the secondcell 1506. In other words, the conditional handover may include one ormore conditions related to a mobility state corresponding to a secondcell 1206 that the first wireless device 1202 wants to be handed overto.

According to aspects, while not illustrated in FIG. 15 , in some cases,the conditional handover command may be based, at least in part, onprior measurement information or prior location information associatedwith at least one of the first wireless device 1502 or the second cell1506. For example, in some cases, the network node 1508 may receivemeasurement information or location information corresponding to one ormore cells in the network (e.g., the second cell 1506) at some time inthe past, as described above. Based on this prior information, thenetwork node 1508 may generate and transmit the conditional handovercommand to the first wireless device 1502 with one or more conditionsbased on the prior information corresponding to the one or more cells(e.g., the second cell 1506).

At step 3, the first wireless device 1502 may take one or more actionsbased on the conditional handover command. For example, in some cases,the first wireless device 1502 may receive one or more signals from thesecond cell 1506 and determine based on the one or more signals, amobility state corresponding to the second cell 1506.

Additionally, in some cases, taking one or more actions may includedeciding whether or not to handover to the second cell 1506 based atleast in part on the one or one or more signals and the one or moreconditions in the conditional handover command. In some cases, decidingwhether or not to handover to the second cell 1506 may include, forexample, initiating a handover procedure to hand over to the second cell1506 if the one or more conditions are satisfied based at least in parton the one or more signals. For example, in some cases, if the firstwireless device 1502 determines that the determined mobility stateinformation corresponding to the second cell 1506 satisfies one or moreof the conditions in the conditional handover command, the firstwireless device 1502 may decide to initiate a handover procedure to handover to the second cell 1506. Additionally, deciding whether or not tohandover to the second cell 1506 may, in some cases, include decidingnot to hand over to the second cell 1506 if the one or more conditionsare not satisfied based at least in part on the one or more signals. Forexample, if the first wireless device 1502 determines that thedetermined mobility state information corresponding to the second cell1506 does not satisfy one or more of the conditions in the conditionalhandover command, the first wireless device 1502 may decide not toinitiate a handover procedure to hand over to the second cell 1506.

At step 5, if the first wireless device 1502 decides to handover to thesecond cell 1506, the first wireless device 1502 may take one or moreactions, such as performing an access procedure and establishing aconnection with the second cell 1506.

Additionally, while not illustrated, if the first wireless device 1502is handed over to the second cell 1506, the network node 1508 mayreceive an indication that the first wireless device 1502 has beenhanded over to the second cell 1506, for example, based on theconditional handover command. In some cases, the indication that thefirst wireless device 1502 has been handed over to the second cell 1506may be received from at least one of the second cell 1506 or the firstwireless device 1502.

The terms “network” and “system” are often usedinterchangeably. A CDMA network may implement a radio technology such asUniversal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includesWideband CDMA (WCDMA) and other variants of CDMA. cdma2000 coversIS-2000, IS-95 and IS-856 standards. A TDMA network may implement aradio technology such as Global System for Mobile Communications (GSM).An OFDMA network may implement a radio technology such as NR (e.g. 5GRA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11(Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA andE-UTRA are part of Universal Mobile Telecommunication System (UMTS). LTEand LTE-A are releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE,LTE-A and GSM are described in documents from an organization named “3rdGeneration Partnership Project” (3GPP). cdma2000 and UMB are describedin documents from an organization named “3rd Generation PartnershipProject 2” (3GPP2). NR is an emerging wireless communications technologyunder development.

The techniques described herein may be used for the wireless networksand radio technologies mentioned above as well as other wirelessnetworks and radio technologies. For clarity, while aspects may bedescribed herein using terminology commonly associated with 3G, 4G,and/or 5G wireless technologies, aspects of the present disclosure canbe applied in other generation-based communication systems.

In 3GPP, the term “cell” can refer to a coverage area of a Node B (NB)and/or a NB subsystem serving this coverage area, depending on thecontext in which the term is used. In NR systems, the term “cell” andBS, next generation NodeB (gNB or gNodeB), access point (AP),distributed unit (DU), carrier, or transmission reception point (TRP)may be used interchangeably. A BS may provide communication coverage fora macro cell, a pico cell, a femto cell, and/or other types of cells. Amacro cell may cover a relatively large geographic area (e.g., severalkilometers in radius) and may allow unrestricted access by UEs withservice subscription. A pico cell may cover a relatively smallgeographic area and may allow unrestricted access by UEs with servicesubscription. A femto cell may cover a relatively small geographic area(e.g., a home) and may allow restricted access by UEs having anassociation with the femto cell (e.g., UEs in a Closed Subscriber Group(CSG), UEs for users in the home, etc.). A BS for a macro cell may bereferred to as a macro BS. A BS for a pico cell may be referred to as apico BS. A BS for a femto cell may be referred to as a femto BS or ahome BS.

A UE may also be referred to as a mobile station, a terminal, an accessterminal, a subscriber unit, a station, a Customer Premises Equipment(CPE), a cellular phone, a smart phone, a personal digital assistant(PDA), a wireless modem, a wireless communication device, a handhelddevice, a laptop computer, a cordless phone, a wireless local loop (WLL)station, a tablet computer, a camera, a gaming device, a netbook, asmartbook, an ultrabook, an appliance, a medical device or medicalequipment, a biometric sensor/device, a wearable device such as a smartwatch, smart clothing, smart glasses, a smart wrist band, smart jewelry(e.g., a smart ring, a smart bracelet, etc.), an entertainment device(e.g., a music device, a video device, a satellite radio, etc.), avehicular component or sensor, a smart meter/sensor, industrialmanufacturing equipment, a global positioning system device, or anyother suitable device that is configured to communicate via a wirelessor wired medium. Some UEs may be considered machine-type communication(MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include,for example, robots, drones, remote devices, sensors, meters, monitors,location tags, etc., that may communicate with a BS, another device(e.g., remote device), or some other entity. A wireless node mayprovide, for example, connectivity for or to a network (e.g., a widearea network such as Internet or a cellular network) via a wired orwireless communication link. Some UEs may be consideredInternet-of-Things (IoT) devices, which may be narrowband IoT (NB-IoT)devices.

Certain wireless networks (e.g., LTE) utilize orthogonal frequencydivision multiplexing (OFDM) on the downlink and single-carrierfrequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDMpartition the system bandwidth into multiple (K) orthogonal subcarriers,which are also commonly referred to as tones, bins, etc. Each subcarriermay be modulated with data. In general, modulation symbols are sent inthe frequency domain with OFDM and in the time domain with SC-FDM. Thespacing between adjacent subcarriers may be fixed, and the total numberof subcarriers (K) may be dependent on the system bandwidth. Forexample, the spacing of the subcarriers may be 15 kHz and the minimumresource allocation (called a “resource block” (RB)) may be 12subcarriers (or 180 kHz). Consequently, the nominal Fast FourierTransfer (FFT) size may be equal to 128, 256, 512, 1024 or 2048 forsystem bandwidth of 1.25, 2.5, 5, 10, or 20 megahertz (MHz),respectively. The system bandwidth may also be partitioned intosubbands. For example, a subband may cover 1.08 MHz (e.g., 6 RBs), andthere may be 1, 2, 4, 8, or 16 subbands for system bandwidth of 1.25,2.5, 5, 10 or 20 MHz, respectively. In LTE, the basic transmission timeinterval (TTI) or packet duration is the 1 ms subframe.

NR may utilize OFDM with a CP on the uplink and downlink and includesupport for half-duplex operation using TDD. In NR, a subframe is still1 ms, but the basic TTI is referred to as a slot. A subframe contains avariable number of slots (e.g., 1, 2, 4, 8, 16, ... slots) depending onthe subcarrier spacing. The NR RB is 12 consecutive frequencysubcarriers. NR may support a base subcarrier spacing of 15 KHz andother subcarrier spacing may be defined with respect to the basesubcarrier spacing, for example, 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc.The symbol and slot lengths scale with the subcarrier spacing. The CPlength also depends on the subcarrier spacing. Beamforming may besupported and beam direction may be dynamically configured. MIMOtransmissions with precoding may also be supported. In some examples,MIMO configurations in the DL may support up to 8 transmit antennas withmulti-layer DL transmissions up to 8 streams and up to 2 streams per UE.In some examples, multi-layer transmissions with up to 2 streams per UEmay be supported. Aggregation of multiple cells may be supported with upto 8 serving cells.

In some examples, access to the air interface may be scheduled. Ascheduling entity (e.g., a BS) allocates resources for communicationamong some or all devices and equipment within its service area or cell.The scheduling entity may be responsible for scheduling, assigning,reconfiguring, and releasing resources for one or more subordinateentities. That is, for scheduled communication, subordinate entitiesutilize resources allocated by the scheduling entity. Base stations arenot the only entities that may function as a scheduling entity. In someexamples, a UE may function as a scheduling entity and may scheduleresources for one or more subordinate entities (e.g., one or more otherUEs), and the other UEs may utilize the resources scheduled by the UEfor wireless communication. In some examples, a UE may function as ascheduling entity in a peer-to-peer (P2P) network, and/or in a meshnetwork. In a mesh network example, UEs may communicate directly withone another in addition to communicating with a scheduling entity.

In some examples, two or more subordinate entities (e.g., UEs) maycommunicate with each other using sidelink signals. Real-worldapplications of such sidelink communications may include public safety,proximity services, UE-to-network relaying, vehicle-to-vehicle (V2V)communications, Internet of Everything (IoE) communications, IoTcommunications, mission-critical mesh, and/or various other suitableapplications. Generally, a sidelink signal may refer to a signalcommunicated from one subordinate entity (e.g., UE1) to anothersubordinate entity (e.g., UE2) without relaying that communicationthrough the scheduling entity (e.g., UE or BS), even though thescheduling entity may be utilized for scheduling and/or controlpurposes. In some examples, the sidelink signals may be communicatedusing a licensed spectrum (unlike wireless local area networks, whichtypically use an unlicensed spectrum).
